ReceptionRating · Positive reviews · Number of ratings

ChargerSync holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: tado° has 778 ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 43% of tado°'s written reviews are positive against 7% of ChargerSync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

tado° ships an update weekly, ChargerSync every 2 months. The most recent releases landed on September 28, 2026 and September 30, 2026 respectively.
